    I successfully executed this script in Excel-2013 on a password protected workbook created in Excel 2003.

    Followed the following steps:

    Developer --> Record Macro (give a name, then do some clicks)

    Macros --> take the macro you created for edit.

    Replace the Macro with the whole function below:

    Sub PasswordBreaker()
        'Breaks worksheet password protection.
        Dim i As Integer, j As Integer, k As Integer
        Dim l As Integer, m As Integer, n As Integer
        Dim i1 As Integer, i2 As Integer, i3 As Integer
        Dim i4 As Integer, i5 As Integer, i6 As Integer
        On Error Resume Next
        For i = 65 To 66: For j = 65 To 66: For k = 65 To 66
        For l = 65 To 66: For m = 65 To 66: For i1 = 65 To 66
        For i2 = 65 To 66: For i3 = 65 To 66: For i4 = 65 To 66
        For i5 = 65 To 66: For i6 = 65 To 66: For n = 32 To 126
        ActiveSheet.Unprotect Chr(i) & Chr(j) & Chr(k) & _
            Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) & _
            Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
        If ActiveSheet.ProtectContents = False Then
            MsgBox "One usable password is " & Chr(i) & Chr(j) & _
                Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & _
                Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
             Exit Sub
        End If
        Next: Next: Next: Next: Next: Next
        Next: Next: Next: Next: Next: Next
    End Sub
